T Application filed November .12, 1920'. Serial No. 147.877;

Thisinvention relates more particularly to an improved flat metal terminal, provided with aperforatedhead-or end, which may he slipped over a binding post stud and secured e thereto, the head of the terminal .beingofiset, so that successive conductors may be mounted on the same bindingpost so as to lie' on opposite sides of a diametralplane' 7 1 It is frequently desirable to attach to. the

[l0 samebi'n post a. plurality of conductors,

leading outward therefrom. in substantially the same direction and when the conductors are provided with the ordinary terminals, they do not stack properly on the bindirigpost stud, and cannot be assembled in substantiallyve'rtical planes, but must be fanned out.

The object of our improvement, therefore, is to provide terminals, of sheet metal or the like, which maybe attached to successive conductors, so that theterminal heads will be oif-set inoppodte directions, that is, on one sidd or the other of the axes of the respective v conductors. In this way, rights and lofts are provided, so that'the terminals may be con-.

veniently stacked, as theyare placed over the binding post stud and the conductors lie in parallelfrelation and may extend outward from the binding post in substantially the same direetiom Obviously, this arrangement will facilitate attaching a plurality of conductors to the same binding post withoutthe necessity of. farming them out thereby provides.:a

more compact arrangement, giving a neater an ppe a r r 1 A further objwt isto provide terminals'of this character, which. may .be 7 blanked "or punchedout of suificientlyhegvy s'heet metal, and provided with clip lugs, which may be 40 bent to one side or the othen bf the terminal pieces for securingthen'i to the respective conductors, so that-the of the terminals will be elf-set to one side or the other "of theaxis of the conduction} The conductor holding clip lugs" preferably ai'rangedg'in pairs with a-space therebetween, for soldering the terminal. to the conductor, the arrangement such as to provide for a secure attachment of the terminal'to the conductor, as well 7 o as'the possible conductivity across the l ,v For the purpose of illustrating our improved terminal and the arrangement for ab.

* taching thesame, referenee may be had to the jvide accompanying drawings, in. which Fig. 1 shows the sheet metal terminal as blanked out or punched out and before the conductor securing clips or lugs-are bent over; Fi 2 shows the terminal with the securing cli bent up so that-the off-set of the head will b: to the right of-the conductor; Fig. 3 shows the securing clips bent so that, when the terminal'is secured'to the conductor, the head thereof will be ofi set to the left of the axis of the cond ctor; Fig. 4 shows the stacking of the term cessively Fig. 5 represents one of the terminals secured to a conductor, with the joint .therebetween protected by a sleeve, and Fi 6 represents the protecting sleeve of Fig. 5 efore it is coiled about the joint.

Referring to the drawings, it will be seen that, as shown in Fig. 1, the terminal ma be punched or blanked out of sheet meta with an annular washer-like head or tip A of ample width togive good contact, the head being provided with a perforation B to fit the stud of any desired bindin post. Preferably the metal of the terminal is of ample provided with an arm C taperingly connected at D with the washer-like head, so as to proeat mechanical strength so as to prevent reaking at this point, and, at thesame time, offer the least resistance to the passa e nalsgwhen rights andleft's are suc-. mounted on the binding post stud;

thickness to provide good conductivity and portion of .the"

of the current. The arm C is preferablyo set from the head A, so that its lateral edge 'E is tangential tothe outer circle of the annular head, as indicated in Fig. 1. The inner edge of F of the arm 0 preferably extends radially or lies substantially in a jdiametral Plane passing through the center of the an nular-head A. V

. The unched' or blanked out terminal is prefera ly provided with two clip lu s G, ex- .tendinglaterall from the tangentia edge E and adapted to bent or foldedover, either upward and. over toward the inneredge F U 1 the terminal as indicated in; Ei'g.' 2, or downward and over toward the ed F, as

indicatedin Fig. 3. In this way,'the pair gficlip lugs G is adapted for the end 'of the conductor H, which will be held therecourse, depending upon the size of the conductors to which they are to be attached, so as to provide for ample strength and the desired conductivity.

As previously pointed out, the advantage of our improved terminal is that a plurality of conductors may be readily secured to the same binding post by alternately mounting thereon right and left terminals, as indicated in Fig. 4. In this way, it will be seen that. the terminals stack so that the conductors or theclips securing the terminals to the conductors will not interfere and the conductors may be closely packed, that is, substantiall in parallel relation, Whichcannot be satis actori-ly done with the usual form of terminal. o

;In this form of terminal, where the terminal head is securel clamped to the "binding post, it frequently appens that, from excessive handling of the wire conductors, the latter may break off at the terminal, for the sity, removed in order to attachthe conductor to the terminal. In order to prevent this, as

'far' as possible, and protect the joint between the terminal and the conductor, a sleeve L of thin sheet metal isfir'eferably lined with insulating material and rolled around .and

clamped over the joint, substantially as in- Fig. 6 represents the condicated inFighd t 's protecting sleeve, with the struction of insulating pad or member shown with one corner turned back.

when the terminal blanks arepunched out of suitable sheet metal in the size desired, the conductor retaining clips G, which extend from the tangential ed e, maybe bent in an easy curve back over t e fiat surface of the metaltoward the inner-edge F, which, as previously ointed out, is parallel to the edge E and su stantially in a plane passing are provided through the center of the opening 13., The

lugs or clips may be bent either as shown in -the binding post. Obviously, by arranging the terminals and conductors in this manner, two,-three or four or any desired number of terminals may be assembled on the binding post stud, with the conductors in close prox imity', without any interference between the joints or.connections between the respective conductors and terminals. As a further protection for the joint, the latter may be enclosed, as indicated in Fig. 5,. by a metal sleeve lined with insulating material and in this manner the joint is fully protected and insulated.

It will be understood that the form of terminal shown represents the preferred form, but we do .not wish to be limited to the specific details of constructionnor tothe method of assembly for various modifications in the f arrangement and details thereof may be made without departing from the spirit and scope of the invention.

1. A terminal for conductors, comprising a washer-like head, an arm extending therefrom, said arm being olf'center, so that its outer ed e is substantiallytangential to said washer cad, and conductor holding clip lugs extending from said tangential edge and adapted to be bent over the conductor on one side of the, arm to form rights and lefts. F protecting and insulating covering is of neceshead, while the inner edge of said arm is substantially radial and parallel with said tangential edge, and conductors securing clips extending from said tangential edge and adapted to be bent over toward the radial edge for securing the terminal to the cona a ductors.

From the above, it will'be understood that and on the other side ,with the head to the left, thereby facilitating the formation of rights-and lefts.
